Make accurate information interesting — never the reverse.

Parenting content is full of confident nonsense. Our standard is different, and it’s public:

The rules we publish by

• Every factual claim is sourced. Posts, guides, emails — each carries its citations, on the slide or on the page.
• We verify before we publish. A claim enters our internal evidence database only after the source is confirmed to exist and to actually support the statement as worded — title-only citations don’t count.
• Source hierarchy. We prefer, in order: systematic reviews and meta-analyses; strong peer-reviewed studies; professional medical organizations (AAP, ACOG); government health agencies (CDC, NIH); major academic institutions and children’s hospitals.
• Nuance survives. A single small study is never presented as settled fact. Correlation is not upgraded to causation. Where the evidence is mixed, we say so.
• No invented anything. No fabricated statistics, studies, experts, or quotes — ever. If we can’t verify it, we don’t publish it.
• Corrections are public. If we get something wrong, we fix it and say we fixed it. Spot an error: wavelengthparenting@gmail.com.
